Karyotype analysis of chub, Squalius cephalus (Linnaeus, 1758) (Teleostei: Cyprinidae) from Karasu River, Erzurum, Turkey
The karyotypic characteristics of chub, Squalius cephalus have been investigated by examining metaphase chromosomes spreads obtained from gill and kidney tissues. The fish used in the study were caught with fishing nets from Dumlu Stream, one of the main tributaries of the Karasu River. The live fish were transported to the laboratory, kept in a well aerated aquarium before analysis and then...

متن کاملPhylogeny of the gudgeons (Teleostei: Cyprinidae: Gobioninae).
The members of the cyprinid subfamily Gobioninae, commonly called gudgeons, form one of the most well-established assemblages in the family Cyprinidae. The subfamily is a species-rich group of fishes, these fishes display diverse life histories, appearances, and behavior. The phylogenetic relationships of Gobioninae are examined using sequence data from four loci: cytochrome b, cytochrome c oxi...
متن کاملSeasonal variations in the fatty acid profiles of the liver and muscle of Squalius cephalus (Teleostei: Cyprinidae) living in Tödürge Lake (Sivas, Turkiye)
In this study, seasonal variations in the fatty acid profiles of the liver and muscle of Squalius cephalus from Tödürge Lake were determined by Gas Chromatography (GC). C22:6 n-3, C20:5 n-3, C20:4 n-6, C18:1 n-9, C18:1 n-7, C16:1 n-7, C18:0 and C16:0 were the principal fatty acids showing the highest levels in the muscle and liver of Squalius cephalus in all seasons. Although C22:6 n-3, which i...
